<< Hi All, 
 I concur with Weazle's observation and suggestion. As mentioned last year, my
 first coil (ca. 1960) was almost exactly 455KHz, which I a friend and ran on
 the roof of an apartment building in NYC, naturally, near a maze of antennas.
 Needless to say, there was extreme consternation among the locals, and the
 "Friendly Candy Co." truck was in the area next day. About a 10-20KHz drop in
 frequency should eliminate a majority of the problem.

I dont think i can lower the frequency much at all.I have tried top 
capacitance and it really gets hard to tune.That leads to QUICK MOSFET 
heating and then its death.

I just got a nice CPU heatsink with fan today and will install it and see how 
heating goes.

BTW-my old fan mysteriously died.No heating.It has surface mount ICs and 
such.Could it have been killed from output from the secondary?
